Theinnerend,otcutterbar 28, thatis thetend oppositethe end of the spring30, is proygidedj with aired 32connec-tedto; operating hand of this bell'crank lever is attached to thearw v ment; ofg-thej armature 40 -away from; the poles that when the electromagnet is energized the arm 39 will be moved upwardly about the pivot 36 to draw the arm 37 away from the cutter bar 28 for a purpose to be hereinafter described.

referred to is carried on a shaft 43 and this shaft carries a ratchet 44 which is adapted to be engaged by a pawl 45 resiliently'mounte d in the arm 39, this pawl being engag'eable with the ratchet upon energization of the electromagnet 41. The pawl'and "ratchet mechanism constitutes a brake or'stop for the feed roller.

The cutter blade 34 cooperates Witha fixedblade or cutter bar 46 mounted in a block 47 the paper taken from the roll 13 passing between the feed rollers 8 and 11 along thetop of the fixed cutter bar 46 to andbetween the feed rollers 10 and 12. I

The motor for driving this machine is designated 50 and itsarmature shaft is provided with a pinion 51 meshingwith gear 52" gear 59 meshing with gear 60 on the shaft 57'" this gear meshing with gear 12 on the shaft .of the lower feed roller 12whereby the feed roller is driven.

The shaft 25 of the doctor 'roll carries a gear 61 meshing with broad faced gear 62 on the end of the shaft 14. This gear 62 meshes with a gear 63 on a stub shaft 64 carrying gear 65 on its inner end meshing with gear I v shoe is adapted to ride 1n a slot or groove 86;

66 integral with glue roller 1.6.

The driving mechanism justdescribed pro vides, as will be appreciated, apparatus fori constantly driving the feed rollers 10 and12,- the gluing roller 15, glue'roller 16 and the the circuit 'of the doctor roller 26 as long as motor 50 is closed.

The machine of this application is equipped to operate intermittently, that is to say, will run off a predetermined length of paper from the roller 13 and then stop, cut the paper off, 1

the severed I piece 'of paper belng passed through the remainder of the machine, that is, over the gluing roller 15 to be discharged, the gluing roller and the feed rollers 10 and 12 which are between the gluing roller and the knife continuing in operation as just mentioned above until the motor circuit is opened.

' The mechanism .whereby part of the apparatus is operated intermittently without interfering with the constant operation of the re-" mainder of the apparatus will now be de-' scribed. 9 The stud 48 carrying the gear 55 and rotor '56 is equipped with a gear 69 the sideof'which The gear 55 in turn adjacent the gear 55 is equipped with ratchet teeth 70. This gear 69 is only rotated intermittently. To provide this intermittent operation of this gear the rotor '56 is equipped with a pawl 71 set into the periphery of the V rotor 56. This pawl is provided with a slot The feed roller 11 which has already been- 7 2. adapted tolrecei've underlcertainlconditions a pivoted locking lever or detent 73. The pawl 71 is provided with a finger 74 against spring being set-intoaerator "56 as will be seen from Fig. 6. As long as the pivoted fingerorlo'cking lever 73 is in the slot 72 the pawl/Z1 is held inoperative position. It is shown in this position in Fig. 6. Under these conditions thespring 7 5 is compressed. When pr g i tantly bearing, this the locking finger or. lever'z73 =is',-moved out;

of the slot 72 then the spring 75 functions to; force the pawl 71 into engagement iwith 'the' teeth or ratchet 70. onltheside .ofithe'gear 6,9,thereby coupling the gear 69 to the gear 55 or rotor 56..

The gear 69 is in constant mesh with a gear 76 on a shaft 77. On the. other end'of this shaft is'a gear 7 8 inv constant mesh with gear 7 9 on the shaft 43 carrying the feed roller.11.x

Consequently rotation ofthe gear 69 will ef-- fect rotation of the feed roller 11 and inasmuch as the gear 69 is only. rotated intermittently the roller '11 is .so rotated. wThe rotor 56 is provided; on its'face with a contact plate 80 suitablyl insulated from the rotor and this plateSO' is adapted tocooperate with contactss8l-and 82 carried bya gear plate 83. I might say at this point that the gear 83-is normallystationary and only is rotated to adjust thetiming of the machine,

as will be brought out hereinafter.

Secured to the inner sideof the gear ;or.

plate 83 is a plate 84 carrying a shoe 85'. This gages this notch in the pawlthe pfawl will be f retractedffrom contact with the ratchet teeth 7 0 on the side-of the gear 69 so as to uncouple the gear 69 from'the rotor 56. a

The. setting of theshoe .85 on the periphery" ofthe rotor 56 as well as the setting of the contacts 81 and 82 with respectto the contact plate 80Lis varied soas to varythe length of paper out at each operation of the machine I by means of a pinion gear "88 meshing with the teethof the gear plate '83., This gear is carriedon a shaft 89 operated by hand wheel 90 so that'by rotating the'handwheelrotation is impartedto gear plate 83 with-a cor-' responding change with respectto plate 80 and setting of shoe 85 p 'e 9 The operating lever 33 which hasbeen mentioned above and which when depressed' will raise the knife-34 to. its upper position, as ilwith respect to the of operationwillbe gone; through as before,

it-being appreciated, however,-that the de-' tent or locking lever 7 3 will not be actuated by the pin 106 to release the clutch pawl 71 so that the feed roller ll will agaiirbegin to rotate until the-rotor 56 reaches the position'shownin Fig. 1, in other words, reaches the position where the 'detent 73 is brought into'engagement with the pin 106; Conse- 1m quently if no adjustment is made the same length of paper is cut oil at each operation ftheknife: "If'it is desired to Vary the length of paper tape being cut off then the hand wheel 90 is rotated in one direction or'the other to rotate the pinion gear 88, this gear rotating thegear plate 88 to vary the setting of the contacts 81, 82 with respect to the contact" plate 80 and the position of the shoe 85 with 203 respect to the'time of its engagement with the notch 87 in the locking pawl 71 1.
